Straight-line wind damage hit Herkimer and Montgomery counties, meteorologist Brian Montgomery said. The storm traveled from west to east along a 30-mile path, most intensely in a 40-minute burst that started just before 4 p.m. In the town of Minden, a barn collapsed on Fordsbush Road, officials said.

"While the damage path was sporadic," a weather service summary says, "there were pockets of intense damage ... mostly from snapped and uprooted trees along the duration of the path."

The weather service survey team found no deaths or injuries from the storm, which knocked out power to more than 20,000 customers of the area's two major utilities at one point later Thursday.

By Friday evening, about 4,700 National Grid customers were still without power. Most of the those were in Fulton, Saratoga and Washington counties, utility officials said.

National Grid, in a Friday update, said crews spent hours repairing downed wires and broken poles and restoring service. Another 200 or so NYSEG customers were without power in Washington County as Friday night approached.

Montgomery County's emergency management director, Jeffrey Smith, said the town of St. Johnsville had significant damage.

There were no flooding issues, Smith said.

Rain showers on Friday morning and early afternoon cleared up as clouds decreased, making for better viewing of nighttime fireworks displays scheduled for Albany's Empire State Plaza and other venues.

Saturday will be mostly sunny with a high temperature in the 80s, said weather service meteorologist Ian Lee.

Sunday is expected to be cloudier, but also warmer and still dry, Lee said.
